Abstract (en)

A ternary signal input circuit includes two inverters having opposite hysteresis characteristics, respectively, a NOR gate for producing an output signal indicative of an inversion of the logical sum of output signals from the inverters, and a AND gate for producing an output signal indicative of the logical product of output signals from the inverters. The ternary signal input circuit, composed only of digital components, converts a ternary signal supplied through a transformer into binary signals and outputs the binary signals. The ternary signal input circuit has a relatively simple circuit arrangement and will take up a relatively small area on an LSI chip when it is incorporated into the LSI chip. <IMAGE>
